Thanks for the idea, Charl! `/sbin/apcupsd --killpower` indeed kills the power when called not in shutdown sequence. Note that `/sbin/shutdown -H now` and `exit 99` is not necessary here as apccontrol does shutdown anyway.
Your workaround works for me as well! Though I made some additions to proposed /etc/apcupsd/doshutdown script: #!/bin/bash # # Duplicate stdout and stderr to log so we can check it later exec > >(tee -a /var/log/killpower.log) exec 2>&1 # create a timestamp date # stop apcupsd to prevent simultaneous access to serial port (THIS IS IMPORTANT!) echo Stopping apcupsd /bin/systemctl stop apcupsd # just to be sure pkill apcupsd # stop important services to make sure they stopped before power is killed echo Stopping important services /bin/systemctl stop pacemaker echo Killing power /sbin/apcupsd --killpower echo Done. echo One can modify this script to his/her needs by replacing line `/bin/systemctl stop pacemaker` with what is appropriate for his/her system. Also make sure that at the point `/sbin/apcupsd --killpower` is executed you have enough time to shut down rest of the system. By default the power will be actually killed in 20 seconds after the call. You can check what timeout is set in your UPS with command apcaccess|grep DSHUTD DSHUTD : 120 Seconds As you see my UPS will kill the power in 120 seconds after `/sbin/apcupsd --killpower` called. To change this value you should execute `systemctl stop apcupsd`, run `apctest`, then choose '5) Program EEPROM', choose '8) Change shutdown delay', execute `systemctl start apcupsd`. In manual it is stated that you can also set this value in variable SLEEP in /etc/apcupsd/apcupsd.conf, and then in apctest choose '14) Set EEPROM with conf file values' - but that DON'T work for me, probably it is a bug of apcupsd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634572 Title: APCUPSD does not send killpower command to UPS (only happens on Ubuntu 16.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apcupsd/+bug/1634572/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
